This reminds me. Why hasn't anyone asked what TimeCube guy's opinion is? Clearly the reason we can't find it is because we have been educated stupid, and not because oceans are giant and planes are small and planes tend to turn into many smaller parts when they hit the ocean.

meow said the dog:What happened is known by me. The French lack accuracy. I cannot use the ability of me to have interference in the affairs which are international but shake the head of me at these searchings.

But then I figured you'd know that by the handle and the fact you've been here for a couple of years.

gfid:This has probably been asked by someone in another thread, but couldn't they have an automated mayday in case the plane impacts something or even loses altitude very rapidly?

New aircraft certified after a certain date, lets say 2001 and beyond, have ELT that operate on 406 MHz. They are water activated and programmable for certain country and aircraft serial number data. Each of the emergency slides on the aircraft may also have a smaller ELT because they can double as life rafts, and you can have a personal ELT but airlines do not have them on their life vests. When an ELT goes off it talks to a satellite network and the coast guard or local equivalent know about it. It sucks when your ELT goes off by accident because they will still show up even if it locates you in a hangar. If the aircraft was grandfathered in to a specific certification you can get a waiver on current certification requirements. This is done so rule changes tomorrow will not impact aircraft built 40 years ago. That being said the airline can always make it a requirement to have one, and the airlines insurance company can do that too. If they hit the water and sank then the ELT will not have much opportunity to do anything.

ELTs can be disruptive too because the strongest signal wins. The aircraft ELT can be broadcasting but if all your people are on the life raft and it floats away, the life raft ELT signal will be blocked by the stronger aircraft ELT, and the rescuers will be looking for the aircraft and not the life raft. There are discussions on being able to remotely deactivate an ELT signal for this scenario but there are trade-offs to that approach.
